APEARATUS For. WITHDRAWING FIBERS, MORE PARTICULARLY Hoasiiriaiias, 'Enola I A BUNDLE.

B e ity known that I, OsKAn, Winsmn, a sulnectoi1 the German AYEmperor, Aand resi- .dent of Mittelstrasse '2,l Forst-Lausitz, Germany, have invented new and useful Improvements in or lRelating .to Apparatus' for VVithdrawing Fibers, More Particularly Horsehairs, from a Bundle, of which the following is a specification.

This invention relates to a device which, on being introduced in a stationary bundle of horse-hair or fibers, always seizes a certain number of hairs `and partly withdraws them from the bundle.

In known devices for withdrawing single horse-hairs a pair of pincers, sometimes with an adjustable jaw, is intermittently introduced into the bundle of fibers and withdraws a number ofl fibers, mostly two -or three. In such a case it may happenthat the gripper device .does not seize any hairs,

. when it'engages with a gap produced by the removal'of hairs during the preceding operation,r and not yetv filled with new hairs. ,This drawback is avoided according to thisinvention, by the gripper device first seizing alarger number of fibers than desired, and

vonly separating `therefrom the desired number, and withdrawing onlyy the latter, while To that end,

of hairs to a small depth and takes up a whole layer of 'bers A clamping lever is vthen moved inthe gripper device, which clampstwo or three hairs which happen to be exactly in `the angle of the s cythelike gripper.` The' gripper is then withdrawn from the bundle 0f fibers, and removes only the fibers clamped. e

A construction according to this invention is illustrated in the accompanying drawing, in which- Figure l showsy a side elevation, Fig. 2 ya plan, without the bundle of bers, while Fig; 3 shows the Scythe-hire, gripper on an enlarged scale, and Fig.- 4" is a detail viewshowing the engagement of the drum carrying-the reed-entering the bundle of bers and the" grooved cam.

As willbeseenfim Fig. 1, the new` device chiefly consists ofagroovedcam aand ofa gripper" arm' 'c pivoted to. swing vertically and' laterally about a 'd ouble'j'oint Z2. *The gripper arin"c carries a downwardly' pro- Specification of Letters Patent.

jecting arm 1 having apin 2 engaging in the cani groove a",wliereby a vertically reciprocating motion is imparted tothe gripperarm c.

lVhen the grooved cam a is rotated in the direction of the arrow d (F ig. 2), the gripper arm c is moved laterally by means of a pin e eccentrically mounted in the-l grooved A,

cam, and engaging iu the slot f in the gripper arm c. The gripper passes into the bundle of hairs g and takes up, by means of the Scythe-like hook la., the adjacent layers of hairs. Owing to continued rotation of the grooved cam, the spring-controlled clamping leve-r 7c pivoted on the gripper arm c yswings to the left as in Figs. 1 andl :2, causing the spring la (Fig. 3) to strike the stop Z, and a portion of the hairs taken up by the Scythelike hook it, is thus clamped, moved downward `with the gripper during thefurther rotation of the grooved cani, and in that way is partly .withdrawn from the bundle. Si'- multaneously with the passage of the gripper through the bundle g, a reed m enters the bundle below the gripper, in order to prevent the gripper shifting ythe hairs laterally, and to guide them correctly into the hopper q of the spinning spindle p.; The movement of the reed m is brought about Vby the cam groove n onthe grooved cam.

The reed m is carried by -a bar v3 which is slotted as at il, to receive the pin 5 surrounded by the coil spring 6, which tends to lift the reed but permits its yielding downward. The inner end of the bar 3 'is held fin engagement with the cam groove n onv "spun together there with a guide thread uniformly guided through the spindle p, and -thus completely withdrawn from the bundle I claim as my invention: 1.
